Abstract:
The latest incarnation of the GISS series of coupled atmosphere ocean models is now available. ModelE (as it is called) is a complete rewrite of Model II' physics, combined with greater flexibility and more options. These include better representations of the stratosphere, tracer components and various ocean models.

The frozen version that will be used for upcoming IPCC simulations and the ... controls for upcoming model description papers is denoted as ModelE1 (internal version number 3.0). This code can be freely downloaded (as a 1.2MB gzip-ed tar file) from modelE1.tar.gz.

Boundary and initial conditions for all of the template rundecks can be downloaded from fixed.tar.gz (191MB). This is a large amount of data due to things like transient 3-D aerosol concentrations etc. If a smaller selection of data is preferred, please contact us. There are many variants of this data available internally, so if you do not find the configuration you'd like, let us know and we may be able to help you.

Note that this public domain version of the code does not contain some of the more experimental tracer submodules (chemistry, aerosols, dust, cosmogenic isotpes etc.) and only one of the dynamic ocean models. If you are interested using or working with these components, please contact the scientists involved directly. There is however, a great deal of generic tracer coding and enough examples to allow people to develop their own tracer modules if they like. We greatly appreciate community involvement on some of these issues. Please let us know if you intend to use this code by subscribing to the mailing list by sending a message to Majordomo@giss.nasa.gov with a line SUBSCRIBE giss-gcm-users-l in the body of the text. We will then keep you informed about code patches and possible improvements to the configuration.

Documentation is included in the distribution (under directory doc/), and is included below for reference. System requirements and configuration of the distribution for any new system is discussed in detail.
